ZINNO, OF WATERBURY, CONNECTICUT, ASSIGNOR TO THE CHA SE COM-PANIES, INCORPORATED, OF WATERBURY, CONNECTICUT, A CORPORATION APPARATUSFOR POURING MOLTEN METAL Application filed December 30, 1929. Serial No.417,333.

This invention relates to an improvement in apparatus for pouring moltenmetal or other molten material and particularly to an apparatus forpouring molten metal into flasks or molds in connection with castingoperations, though not so limited.

Heretofore, it has been the practice when pouring molten material intoflasks or molds to carry the said material to the molds or flasks from afurnace or other large storagecontainer by means of portablehand-manipulated ladles in order to effectively and properly control theflow of material as it is delivered into such molds or flasks.

The above procedure has been laborious, wasteful and otherwiseineflicient for many reasons, among which may be mentioned the coolingof the molten material before it could be poured into the flasks ormolds, thereby necessitating an excessively-high initial temperature,with the result that oxidation was increased, the molds oftentimeseroded, or the material cooled to such a degree as to imperfectly spreadin the mold.

The main object of this invention is to provide a convenient andreliable apparatus of the type referred to constructed with particularreference to conveniently and effectively controlling the flow of moltenmetal, etc., from a large container, such as a meltingfurnace or otherrelatively large container, into smaller containers, such as flasks ormolds.

With the above and other objects in view as will become apparent fromthefollowing, my invention consists in an apparatus for pouring moltenmetal, etc., characterized by the employment of a delivery-containermounted in a plane below the spout or discharge-opening of arelatively-large storagecontainer with capacity for independent tiltingmovement with respect thereto and positioned intermediate the saiddischargeopening and the flasks, molds, or other receiving-containers,into which it is desired to pour the contents of the storage-container,so that the molten material is delivered from the storage-container tothe receiving-containers through the intermediary of the said 50 tiltingdelivery-container, whereby the flow of molten material from thestorage-contamer into the receiving-container may be readily andconveniently controlled.

My invention further consists in an apparatus for pouring molten metal,etc., charactermed as above and having certain other details ofconstruction and combinations of parts as will be hereinafter describedand particularly recited in the claims.

- In the accompanying drawings:

Fig. 5 is a broken, vertical, sectional view taken on the line 55 ofFig. 2, but on a larger scale; and

Fig. 6 is a vertical sectional view taken on the line 6-6 of Fig. 5, buton a larger scale.

In the embodiment herein chosen for the il lustration of my invention Iemploy a ladleshaped container 10 which I shall for convenience ofdescription hereinafter refer to as a delivery-container and which isprovided 0 with a lining 11 of refractorymaterial and fernlinates at itsforward endin a pouringip The said delivery-container is mounted fortilting movement in a plane below-and preferably with its inner portiondirectly beneaththe spout 13 of a tiltable meltingfuriiace 14 or otherrelatively-large storagecontainer by providing it on its respectiveopposite sides, near the upper edge thereof, with outwardly-projectingbosses 15 and 16, respectively receiving trunnion-studs 17 and 18projecting therein respectively from the upper ends of the complementarycurved arms 19 and 20 of a mounting-yoke 21, which 5 latter is enlargedat its central portion as at 22 for the purpose as will hereinafterappear.

It will be noted from the drawings and particularly in Fig. 5 thereofthat the delivery- 100 container 10 is so mounted that its inner andmost capacious portionlies to the rear of the trunnion-studs 17 and 18,so that when charged with molten material there will be no tendency forit to ti forward b gravity.

For the purpose of ti ting the sai deliverycontainer as required tocause its contents to flow into a mold or flask 23,1 rovide the saidcontainer with a fork-shape hand- 10 and comprismg a pair ofcomplementary L- shaped arms 25 and 26 inclined slightly forward asshown and respectively perforated as at 27 and 28 for the reception ofthe bosses and 16 and secured at their lower ends by means of rivets 29to the opposite side-faces of the said delivery-container. The upperends of the L-shaped arms and 26 just; referred to are united as shownand terminate in' an upstanding handle 30.

To provide for bodily moving the deliverycontamer 10 radially a limiteddistance toward and away from the melting-furnace 14 and to provide forswinging the said container laterally for the purpose as willhereinafter appear, I pass downward through the central portion 22 ofthe yoke 21 a stud 31 upon which the said yoke 15 free to turn and whichhas its lower end threaded into a reciprocating carriage 32 mounted inthe horizontal arm of an L-shaped bracket 33 to which it is secured byplates 34 and 35. The said bracket 33 is secured to the central portionof a cross-bar 35 secured at its respective opposite ends to standards50 and 51.

The stud 31 is mainly designed to position the yoke 21 upon the carriage32 with capacity for horizontal swinging movement but the load isintended to be mainly taken by an anti-friction bearing comprising anupper-race 36 hearing against the underside of the central portion 22 ofthe yoke 21, and a bottom-race 37 located in an annular recess 38 in thesaid reciprocating carriage. The said races have interposed between thema series of balls 39 in the usualmanner of antifriction bearings.

Secured in a longitudinal groove 40 in the underface of the carriage 32is a rack-bar 41, the teeth of which are meshed into by the teeth of apinion 42 mounted upon the inner end of a horizontal laterall -extendingshaft 43 hearing of the bracket 33 and having an upstanding hand-lever45 secured-to its outer end.

It will be seen from the foregoing that the delivery-container 10 ismounted for vertical tilting, lateral swinging, and bodily rectilinearmovement, toward and, away from the melting-'furnace-14, which latteris, as shown, of the tilting type, being provided near its respective oposite sides with forwardly-extending brac et-arms 46 and 47 respectivelyprovided with heavy studs 48 and e5 49 respectively bearing in the upperends of lever generally designated by the numeral 24 in a boss 44 in t ehorizontal arm.

standards 50 and 51 upstanding from the foundation 52 on opposite sidesof the furnace, as clearly shown in Figs. land 2 of the drawings.

As shown, though forming no part of my present invention, the flasks ormolds 23 are preferably mounted upon carriages 53 provided with flangedwheels 56 riding upon rails (Figs. 3 and 4) so that successive flasksmay be presented beneath the pouringlip 12 of the delivery-container 10in rapid succession.

Coming now to the operation of my improved pouring apparatus, let it besupposed that a flask or mold 23 has been positioned beneath thepouring-lip 12 of the deliverycontainer 10. The melting-furnace 14 willbe tilted forward in the usual manner ofsuch furnaces to cause themolten metal therein to flow outward through the spout 13 and into thedelivery-container 10 preferably in a steady stream. The saiddelivery-container will now be rocked by means of the handle 30 todepress its pouring-lip 12 and permit the molten metal. to flow into theflasks 23 preferably as rapidly as the metal is received by the saidcontainer.

When any given flask has been fully charged with molten metal, thedelivery-container is returned to its normal position until anotherflask has been positioned beneath its pouring-lip, meanwhile continuingto receive and store the metal pouring from the spout 13 of themelting-furnace. When the newlypresented flask is in position, thedeliverycontainer will be again tilted forward and downward to pour itscontents into the flask in question, together with the molten metalwhich continues to flow into it from the furnace or otherrelatively-large container.

The delivery-container 10 as before stated may be swung laterally alsoby means of the handle 30 to align its pouring-lip'with the variousopenings in a flask such as 23. In the event that the pouring-lip of thecontainer 10 projects ins ufliciently or excessively so as not to alignitself with the openings in the flasks as they are presented, the saidcontainer may be bodily moved in and out with respect to both thefurnace 14 and the flask 23 by means of the hand-lever 45 acting throughthe pinion 42 and rack 41.

It will thus be seen from the foregoing that by means of my invention- Ihave provided a convenient. reliable and effective apparatus forcontrolling the flow of molten material from the furnace 14 or otherrelatively-large container into receiving-containers, such as the flasks23, with a minimum loss of time, effort, etc., since thedeliverycontainer 10 acts as an intermediate storagecontainer andprovides for the intermittent delivery of molten material into thereceiving-containers while permitting the storagecontiainer to dischargecontinuously if desire It will also be understood that it is notnecessary that my improved apparatus be used in connection with amelting-furnace,

since it is often desired to deliver molten material fromstorage-containers which are not in themselves melting-furnaces.
